       cfv  -  Verify  file  consistency  with .sfv, .csv, .crc, .md5, md5sum,
       sha1sum, .torrent, par, or par2 files


       cfv [-p  dir]  [-v|-V|-VV]  [-r|-rr|-R]  [-n|-N]  [--renameformat  <s>]
       [-s|-S]  [-zz|-z|-Z|-ZZ] [-T|-C] [-m|-M] [-i|-I] [-u|-uu|-U] [--unquote

       [--announceurl   <u>]  [--piece_size_pow2  <n>]  [-t  type]  [-f  file]


       cfv verifies that the files you have are the same  as  those  that  the
       were used to create the checksum file.


       -v     Enable printing of extra messages.

       -V     Disable printing of extra messages. (default)

       -VV    Like -V, but don’t print status line at end either.

       -q     Like  -VV,  but  not even error messages are printed.  Check the
              exit status.

       -Q     Only status lines are printed, but not individual errors.

       --progress VAL
              Set when cfv should display progress bars.  If no, progress bars
              are  never displayed.  If auto, progress bars are displayed when
              the output is to a tty.(default)  If  yes,  progress  is  always

       -r     Recursive  mode  1.   In create mode, make seperate chksum files
              for each dir.

       -rr    Recursive mode 2.  In create mode make a single file  with  deep
              listing  in  it.   Both  recursive modes are equivilant for test

       -R     Disable recursive mode (default)

       -l     Follow directory symlinks in recursive mode. (default)

       -L     Don’t follow directory symlinks in recursive mode.

       -T     Set test mode. (default)

       -C     Set create mode.

       -m     Check only for missing files (don’t compare checksums)

       -M     Check checksums (default)

       -n     Rename bad files.  With -s, also renames misnamed files  to  the
              correct name.

       -N     Don’t rename bad files (default)

       --renameformat string
              Format  string  to use with -n option.  Simply, put any of the 4
              strings %(fullname)s, %(name)s, %(ext)s, and  %(count)i  in  the
              format string, along with whatever other text you wish.
              The default is ’%(name)s.bad-%(count)i%(ext)s’
              In  detail, this is a standard python format string with mapping
              that contains {’fullname’: original filename,  ’name’:  fullname
              minus  extension, ’ext’: extension(including .), ’count’: rename
              attempt}.  If the format string does not contain count, then cfv
              will  append  ’-%(count)i’  to the filename if the first attempt

       -s     Search for misnamed files.  No effect  in  create  mode.   Also,
              keep  in  mind that using -m together with -s will do nothing if
              the checksum type doesn’t include filesizes, and if it does, can
              give false positives if some files have the same size.

       -S     Don’t search for misnamed files. (default)

       -i     Ignore case.  Currently has no effect in create mode.

       -I     Don’t ignore case (default)

       -u     Show unverified files.  If no files in a directory are verified,
              shows dir/*.  If no files in a  directory  or  its  subdirs  are
              verified, shows dir/**.  Has no effect in create mode.

       -uu    Show  each  unverified  file  individually, no special directory
              handling.  Has no effect in create mode.

       -U     Don’t show unverified files (default)

       -zz    Force making/reading checksum files as gzipped  files,  even  if
              not ending in .gz (mainly useful for "-f -")

       -z     Make gzipped files in create mode.

       -Z     Don’t create gzipped files automatically. (default)

       -ZZ    Never use gzip, even if file ends in ".gz".

       --unquote BOOL
              If  yes,  handle  checksum  files  that  were generated by buggy
              encoders that quote filenames in  checksum  formats  that  don’t
              need  it.   Default is no, since quotes can be a valid character
              in a filename and we don’t want  to  remove  them  if  they  are
              actually part of the filename.

       --fixpaths string
              Convert  all  occurances  of any characters in string to the dir
              seperator for the current platform.  No effect in  create  mode.
              Use an empty string to disable.

       --strippaths VAL
              Strip  NUM  leading  components  from  file  names in test mode.
              Similar to the -p/--strip options of patch.  VAL may be  ’none’:
              leave  exactly  as is, ’all’: strip everything but the filename,
              0: strip the leading driveletter/slash (if any), 1+: strip  this
              many path components in addition.  The default is 0.

       --showpaths VAL
              Show  paths  in  displayed  filenames.   VAL  should  be  one of
              yes/1/no/0/auto/2 or absolute/relative, or one from  first  list
              and one from second joined by a -.  For backwards compatability,
              1=yes,  0=none,   2=auto.    The   default   is   auto-relative.
              Abrieviations  are  accepted.   Examples: --showpaths=y-a always
              shows absolute paths.  --showpaths=n never shows paths.

       -p dir Change to directory before doing anything.

       -f file
              Specify the name of the checksum file to  test  or  create.   If
              file is -, stdin (for -T) or stdout (for -C) will be used.

       -t type
              Specify  the  type  of the file.  Can be sfv, sfvmd5, csv, csv2,
              csv4, sha1, md5, bsdmd5, par, par2, torrent, crc, auto, or help.
              If  the type is help, or an unknown type is given, a list of the
              types and their descriptions will be printed.   The  default  is
              auto,  which  will detect the file type for you.  When creating,
              if type is auto an sfv will be made, unless a different  default
              has been set in the config file.

       --list listset
              Prints  a  raw  listing  of  files  in  the  given set (ok, bad,
              unverified, notfound).  Usually used with -q, but  not  strictly
              needed  since specifying --list will redirect all other messages
              to stderr.

       --list0 listset
              Like --list but files are seperated by a null char.   Useful  in
              combination with xargs -0.

       --announceurl URL
              Tracker announce URL for .torrent file creation.

       --piece_size_pow2 N
              Power  of  two  to set piece size to for .torrent file creation.
              The default is 18, which gives a piece size of 2^18=256KB.

              Print help info.

              Print version of cfv and modules it uses.

       sfv is a Simple File Verify format file
       sfvmd5 is a Simple File Verify format file, using MD5 checksums  rather
       than crc32.
       csv   is   a   Comma  Seperated  Value  file,  with  the  fields  being
       csv2 is a Comma Seperated Value file, with the fields being name,size,
       csv4  is  a  Comma  Seperated  Value  file,  with  the   fields   being
       sha1 is a sha1sum format file
       md5 is a md5sum format file
       bsdmd5 is a BSD md5 format file
       par is parchive v1 format file (test-only)
       par2 is parchive v2 format file (test-only)
       torrent is a BitTorrent metainfo file
       crc is a JPEG Sheriff format crc file


       The  exit  status  of  cfv  can  be  examined to determine what kind of
       errors, if any, occured.

       An exit status of 1 indictates a command line  argument  error,  or  an
       unhandled exception.

       Otherwise, the exit status will be a bitwise OR of:

       2      badcrc  (a  file  had  a  different  checksum than listed in the
              checksum file)

       4      badsize (a file had  a  different  size  than  listed.  Not  all
              checksum file formats include file size)

       8      notfound (a file that was listed was not found)

       16     ferror (some other file error occured when trying to open/read a

       32     unverified (a file was not verified, only with -u)

       64     cferror (a checksum file was not found or not recognized)


       Since different platforms represent  the  path  seperator  differently,
       using recursive mode 2 (-rr) is not recommended for anything other than
       personal usage.  Although the addition of the fixpaths  option  can  be
       used  to  work  around  this, it isn’t guaranteed that whatever program
       others user have will have a similar feature.

       The -s option is not currently implemented for .torrent files.  (Unless
       you also use -m)


       If  no  options  are  specified, the default will be -T -t auto, and it
       will search the current directory for any supported checksum files.

       Force the file to test:
       cfv -f

       Test only the files you have, (avoid file not found errors):
       cfv *

       Create a csv file for all the files in the current dir:
       cfv -C -tcsv

       Create a csv file for only the  zip  files  in  the  current  dir,  and
       specify the filename:
       cfv -C -fsomezips.csv *.zip

       Check  if  all  files  in  current  and subdirs are verified, but don’t
       verify checksums of files that are.  (For  example,  before  writing  a
       directory  to  a  cdr  and  you  want  to  make  sure all the files are
       cfv -r -m -u


       Upon startup, cfv will  test  for  ~/.cfvrc  and  if  it  exists,  read
       configuration  information from it.  The file consists of any number of
       lines, each having a single option name and the value  seperated  by  a
       space.  Empty lines and lines beginning with a # are ignored.

       multiple times, the earlier instances having higher priority.
       #for  example,  the  following  line  would  cause cfv -C -f foo.md5 to
